Patented Dec. 17, 1929 I'OHN O. WAGNER, OF CHICAGO, ILLNOIS SCREEN CONSTRUCTION Application filed November 2.1, 1.927. Serial No. 234,661.

This invention relates to a screen construction for swinging ventilators 'and concerns itself primarily with the construction bctween the screens and Ventilator.

""5 The diiiiculty heretoforel encountered in Screened Ventilator construction existed in the fact that the contacting parts between the ventilator andV screens would not always provide a tight fit when the ventilator was In certain of the prior art devices, arcuate contact rolls have been provided between the vVentilator and screens. Gn account of Variations in width between the ventilator and screens such contact rolls l.15 would not always provide a good lit. Moreover the same were always more yor less costly. In other devices of the prior art, Ythe contact plate on the Ventilator moves the upper screen both outwardly and upwardly.` This naturally requires the upper screen to 'be loosely mountedLa thing which is objectionable. Sometimes this upward movement vbecomes too great for the space afforded whereby the particular structure becomes iml `25 practicable for certain places.

Itis an object of this invention to overcome these objectionable features of prior devices in the provision of simple contact members between the Ventilator and screens, which v Contact members can be cheaply produced,

which can be readily adjusted for Variations in space and which will also produce a good it between the Ventilator and screens when the former is open.

The invention comprises the novel structure and combinations hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings, which il y' 40 lustrate certain preferred embodiments of this invention and in which similar reference numerals refer to similar features in the different Views:

Figure 7 is an enlarged fragmentary. sectional View illustrating amodified contact member and showing in dotted lines the window in tilted position.

Figure 8 is anvenlarged fragmentary sectional vie w of the Window with parts omitted and showing an adjustable contact member.

In referring to the drawings, especially the Figure 1, it will be noted .thatl have illustrated a pivoted or swingable Ventilating section 2 in connection with arwindow l, though the same maybe a wall orthe like. The frame of the Ventilating section comprises an upper angle member 3, a similar lower angle member 4 and side stiles 5, with suitable intermediate framing for supporting the panes. It will be noted that the vertical flanges of the angle membersy 3 and 4 abut is an enlarged fragmentary secthe line Vl-VI of .the adjacent frame members 6 and that the horizontal flange of the member 4 abuts an angle member 8 secured to the adjacent frame member 6. This particular construction allows the Ventilating section to pivot in only one direction. Welded to the side members 5 of the Ventilating section andv s wingable therewith are channel shaped members 9, (Figure 4), Afor bridging the gap between such side member 5 and the adjacent frame member 6 of the window. A leaf spring 9a is secured to the stationary frame member 6 and extends between the members 5 and 6 and bears against the channel member 9 for closing the channel when the ventilator is open toY prevent insects from entering.

Upon the front side of the ventilator section 2, there is a contactv member 10 which issecured at its ends to the side members 5 ofthe Ventilating section. Contact )memberH l0 comprises a'ilat VerticalV portion Yl()a and-an upper portion b which slopes toward and contacts with the glass and frame. Upon the rear side of the Ventilating section, there is another contact member 1l comprising a flat vertical portion 11, and an upper portion 11b which slopes toward and contacts the glass and ventilator frame. The flanges l()b and 1l" of the contact members, on account 'of their slopes may be Vreadily bent upwardly or downwardly in the field for varying the respective distances between the ventilator and the Contact members according to the space afforded by diiiierent struc; tures or locations, and according to the thickness oi' the glass of t'he ventilator.

Upon the upper frame member 6, there are a pair of clips l2, (Figure The -t'u'iic'ti'on of these clips is to coniiiie the 'upper frame member 13 'oiz the upper screen. Upen the stationary side rail 6 adjacent the venti 'tin-g opening, are suitable angle clips 14, to i'vlliic'li angular seats l5 are secured, 'as shown iii Figure 4t, for receiving the lside Vframe members 13a of the screen. Suitable guide bolts 16 tend from the sides lL ofthe upper screen and 'through 'suitable slots l? i'n the side seats l5, whereby the upper screen is Capable ot a limited Vertical ni'o'v'e'nient.` 1 p The lower Vframe member 18 oi the -upper window screen is iiori'iially positio'neda et the contact member l0, shown in Figu 'e '3, while the upper frame member 13 'oir' such screen is confined kbetween the clipvliZ and against the depending poiti'on oit the deformed :portion 7, as shown in Figure '2. The lower Yscreen has an upper fra-me member i9 which is normal-ly retained against Vthe.guard member 11 by securement to a bracket 28 on the frame inembers, (Figure The loi-ver frame member 20 of the lower lscreen 'is supported upon suitable angle clips 2l ysecured Ato an angle member 22 upon Iadjacent traine vmember 6 yas shown in Figure 5.

The 'Contact member l-O may bemade in a substantial arcuate kform comprising a ,plurali'tyof sections at slightinclinations to each other, as indicated by the `members 10C oi :Figure 7 whereby the ventilator will always have a close iit between the screens when open. Instead of sloping rthe flanges ot' lthe Contact members7 they may be inadereitwo parts as shown in Fig-ure 8 in which the depending portion 23 is adjustably lconnected Ato the upper por-tion 24 by a bolt 25 carriedby the inem- Aber 23 and extending through a slot in the member 24. .The depending portion 23 can then be laterally adjusted iior variations in .thickness ofglass or ventilator space.

Normally the parts comprising the upper and lower screen and Jthe intermediate ventilating section occupy the relative positions as shown in Figure 3. rllie Ventilating section ispivoted by tlielugs26 on the side meinbers 5 to suitable lugs or brackets-27 on the -iadjacent side-frame members @fand is adapted to swing as shown in dotted lines in Figure 7. During such swinging movements, the upper screen will be slid upwardly, as is evident from a comparison of Figures 8 and 7. It will be noted that a rolling action arises between the screen frame and the ventilator, and the ventilator will swing a considerable distance before moving the upper screen. It should, however, be noted that the Ventilator 2, in its open position, eiiectively closes the space. between, the screens, as shown in Figure 7.

I Aa'iiiai'vare that many changes may be made, and numerous details of construction may he varied through a wide range without departing 'from the principles of this inveiition, and I Athereiere 'do 'not purposelinitng the patent granted thereon, )otherwise than necessitated 'by the prior art.y

I claim as my invention:
